WASHING MAGHINE Application filed February, 1930. Serial No. 430,988.

tear the clothes, and my object is to devisev a machine of this typewhich will eifectively move the clothes in the tub without undue wearand tear.

I attain my object by means of a construction which may be brieflydescribed as follows. Within a tube is mounted an agitator comprising adisk located adjacent the bote tom of the tub and secured to a sleeveextending upwardly and driven by a drive shaft extending through thebottom of the tub. Up from the disk extend a plurality of cylindricalpins which reach toy a `point abovethe upper surface of a wash for whichthe tub is designed. These pins are preferably positioned about midwaybetween the sleeve and the wall ofthe tub.

The invention is hereinafter more specically described and .isillustrated in the accompanying drawings in which -Fig. l is a verticalsection of a washing machine showing only parts relating to rninvention; and l Fig. 2 a plan view of the same.

In the drawings like numerals of reference indicate corresponding partsin the different i'igures.

Referring to the drawings, l is a, tub formed of metal and shown assupported on the legsQ. Projecting upwardly from the bottom of the tubis a sleeve 3 which extends well above the normal water linev of thetub. Through this sleeve extends s by any suitable means (not shown). Y

Y' Within the tub is positioned an agitator which comprises the `disk4a, the cylindrical sleeve 5 and the upwardly extending pins 6. Thesleeve 5 embraces thesleeve k3 and its upper end is! squared to receivethe squared upper end of the driving shaft t which Will be given anoscillatory'movement by any suitable mechanism. The disk 4a,

it will be noted, is considerably less in diameter than the wall of thetub 1 andrto it, adjacent its rim, are secured the pins 6 which arepreferably cylindrical in form and parallel tothe axis of the agitatorand have f their upper ends formed with hemispherical caps 7, of greaterdiameter than the pins, which prevent injury to the clothes when thelatter are being-,introduced in to thev tub. These pins alsoy extendwell above the normal water level of the tub when the latter contains awash of the size for which the machine is adapted with` .af suflicientAmargin for any probable higher level. When the clothes are introducedinto the tub they lie between the sleeve 5 and the ywall l of the tuband between and not over the pins 6. The wall of the tub is`,` ofcourse, vsmooth and free' fromv projections.v Further they positioningof the pins 6 isrsuch that they .carry the clothes back and forthwithout exerting any materialoutward pressure, thereon. rIh-e clothesare thus thoroughly agitated and swirled through the water withoutcoming into contact with any projecting i pins or surfaces which willcause scuiliing or wear, theresult Vbeingthat the clothes are thoroughlycleansed in a shorter period of time than is possible .with ordinarycon-l structions.V j j What I claim as myinventlon is:

. 1. In a washing machine the combination i of'a tub; an agitatormounted therein to revolve on a vertical axis comprislng'a disklocatedadjacent the bottom of the tub7 a `1 central sleeve extending`above thenormal. water level in the tub, and a Lplurality of upwardlyextending pins carried by the disk yparallel tothe axis of the agitatorand also the tub.

3. A Washing machine constructed as set forth in claim 1 in which thepins are lo-V cated approximately midway between the axis andcircumference of the tub.
